Card Not Activated
What it means
The card is new and has not been properly activated or unblocked by the cardholder.
Why it happens
A newly issued card has not been activated, so the issuer declines transactions until activation is completed.
If you’re the cardholder
Activate the card with your issuer, then try the payment again.
If you’re the merchant
Advise the customer to activate the card; a retry can succeed after activation.
